    Surge Protection: Are SPDs Enough?

    Surge Protection: Are SPDs Enough?

    When it comes to surge protection, your main line of defense for your electronic devices might
    just be a fancy power strip or some other surge protection device (SPD). But if lightning strikes
    or you accidentally overwhelm your electrical system with the number of devices you are using
    simultaneously, a small SPD may not be enough to save your electronics.

    At 24/7 Electric, we always recommend that our customers invest in their electrical safety by
    having a whole house surge protection device installed. Here is a little background info on how
    they work, and why they are worth it.

    What is a power surge?

    To understand why a whole house SPD is beneficial to your home, it helps to better understand
    what a power surge is and when it can happen.

    Essentially, a power surge is a spike in the electrical current that runs through your home. This
    can happen for several reasons, but the two biggest culprits are major appliances and lightning
    strikes. Sometimes when you turn on a high-power electrical appliance, it will spike your
    electrical current as it begins to run and do its job. Dryers, air conditioners, refrigerators, and
    space heaters are just a few of the appliances with the potential to cause a power surge.

    As for lightning strikes, while the likelihood of one hitting your house might seem slim, it is far
    more common for lightning to strike near power lines. If this happens, it can cause a power
    surge forceful enough to destroy devices like computers and televisions.

    Without proper surge protection, your electronics can become sitting ducks for dangerous
    power surges.

    What is whole house surge protection?

    Whole House surge protectors allow the correct amount of electrical current to flow through
    your home normally. But if thy detect a spike in the current that is too high, the protector will
    divert the surge to a ground wire and prevent it from traveling into your home and damaging
    your devices. Rather than relying on small power strips to handle this task, if you have a whole
    house surge protector in your home the diversion takes place directly at your service panel
    rather than each of your outlets.

    Whole House Surge Protection Benefits

    One of the biggest advantages to consider when comparing small SPDs to whole house surge
    protection is the way a power surge will affect your devices that are hardwired into your
    electrical system. Even if you trust your laptop with a simple power sting, what about your
    HVAC unit, or LED lights?

    Power surges don’t always cause damage through your outlets, either. Sometimes they can
    travel through your phone lines, cable lines, or ethernet. But if your whole house surge
    protector stops dangerous currents at their source, they will never reach your devices.

    One of the most important reasons to protect your possessions from surges is because you can
    not always successfully file an insurance claim to have them replaced. Some insurance policies
    do not protect against this type of damage.

    With the enhanced safety and reliability whole house surge protection can offer, 24/7 Electric
    always recommends that our customers consider having it installed by a licensed professional.
